PAPER-TRININIING MACHINE.

SPECIFICATION forming part of Letters Patent No. 594,490, dated. November 30, 189:7.

Serial No. 641,515. (No model.)

To all whom, it may concern,.-

Be it known that I, CHARLES SEYBOLD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain newand useful Improvements in Paper-Trimming Machines, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to machines for trimming the edges of piles of paper-such as books, pamphlets, circulars, posters, and the like.

IIeretofore in machines designed for this purpose but a single cutting-knife has been employed, necessitating four operations of the knife with fourstoppages and four turns of the clamp-plates to bring the untrimmed edges of the bundles successively within the stroke of the knife. Moreover, as each eX- posed edge of the bundle in such older machines has to be brought into the pathway of the knife it has not been possible to supply a gage and ixthe bundles in the exact position required between the clamp-plates for holding the bundles during the trimming operationsV The vexact position of the bundles on the clamp devices has heretofore been determined by guesswork, the position being fixed by measuring with the eye as nearly as possible.

The principal features of my invention, therefore, consist in the entire reorganization of such machines, whereby two of the edges of the bundles of paper may be simultaneously trimmed, thus necessitating but a single turn of the bundles to bring all the uncut edges within the strokes of the knives. This I accomplish by that certain novel construction and varrangement of parts to be hereinafter moreparticularly pointed out and claimed, whereby I am enabled to employ two cutting-knives acting automatically and simultaneously in planes. parallel to each other to trim two edges at a time and in which a gage is provided for the adjustment of the bundles of paper in the exact position required, arranged to automatically move out of the way as the clamp-plates carrying the books or pamphlets are turned to bring the remaining uncutI edges withinthe stroke of knives. There are also sundry other features of novelty and'utility, which will be particularly pointed out as the mechanism is hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of my improved machine. Figs. 2 and 3 are respectively right and left side elevations thereof. Fig. 4 is a rear elevation of same. Fig. 5 is a horizontal section taken on lines 5 5 of Fig. l, and Fig. 6 is a central vertical section of same. Y

The operating mechanism is mounted in a suitable solid and substantial framework A, consisting of side standards B B and bedplate O. Securely bolted on top of the side standards B B are the head-blocks D D, provided with diagonal slots a a. f

E is the knife-bed, a solid substantial metal bar provided with horizontal tracks or guides h b, upon which are mounted in rollers c c the knife-carriages F F, to the depending side plates G G of which are secured the cuttingknives II H, the knives being adjustably secured in vertical slots d d therein by the bolts e c, thus giving a vertical adjustment for the knives within the limits of the slots.

K is the main driving-shaft of the machine, journaled from side to side in the framework and provided withdriving-pulley L at one end and a hand-wheel M at the other keyed thereto. Mounted loosely on this drivingshaft at one end and operated by frictionclutch, to be hereinafter described, is the gear N, which meshes with the large gear-wheel O, mounted on and keyed to the shaft P, which is 'journaled in the framework from side to side. The gear-wheel O carries a stud R, and the shaft P at the other lend the crankarm vS, with stud f, both studs being at the same distance from the center of the 4shaft and coupled with the arms T T by connecting-rods U U, pivoted thereto. The coupling-studs on the outer ends of these connecting-rods, by which the arms T T- are pivoted and retained by caps and bolts g g to the connecting-rods U U, are formed eccentrically on the ends of the arms T T, which arms pas-s through the central slots a ce in the headblocks D D and are rigidly secured in any suitable way to the ends of theknife-bed E.

IOO

The knife-bed also carries stud-rollers h h at each end, which take into the outer slots a in the head-blocks and which serve to steady the movement of the knife-bed and knives. It will be evident from this construction so far described that as the shaft Pis rotated by the gearing N O the knife mechanism will be reciprocated with a downward shearing cut guided by the diagonal slots in the headblocks.

In use, as the connecting mechanism for one of the knives may wear more than the other and as it is evident that the best results can be obtained by providing for an absolutelyuniform pull on each end of the knife-bed, I couple, as above described, the arms T T by eccentric-studs thereon to the connecting-rods U U, so that should either end of the knife connections work loose or wear by loosening the connection with the knife-bed the proper arm T may be turned slightly in the recess and thus take up any wear that may occur.

For clamping and holding the paper to be eut I provide as follows:

Y is the clamp-screw, held in a vertical position by a washer l, set in a recess in the sleeve m, which sleeve is held in place within a suitable depression in the bed-plate C. Secured to this sleeve fm, is the horizontal clamptable A', the clamp-table being thus journaled on the sleeve in the bed-plate, so as to be capable of rotation, as hereinafter described, butunaffected by any movement of the clamp-screw.

Mounted on the clam p-table A' are two vertical guide-rods B B', between which the clamp-plate C' travels up and down on the clamp-screw as the same is rotated in either direction. rlhe clamp-plate C is provided with upper and lower fiat horizont-al plates n n, upon which are secured, by bolts or otherwise, the pattern pla-tes or boards j) p p', these pattern-plates being made of varying sizes to conform to the varying sizes of the books to be trimmed, and the upper patternplates p'p being the exact counterparts of the lower set p p. A form plate or board r is also secured to the clamp-table A, upon which the books or bundles of paper D D rest during the trimming operation.

Mounted on the lower end of the clampscrew Y is a horizontal miter-gear E', which meshes with corresponding miter-gears Il" F', mounted loosely on the main driving-shaft K.

G' is a clutch-collar feathered on the shaft so as to slide in eitherdirection and provided with a circumferential recess s, engaged by the bifurcated ends of a clutch-bar t, which bar passes horizontally through slot u in the front cross-beam of the frame, where it is engaged by the upper end of the vertical arm w of the foot-treadle IT, pivoted to a downward extension of the frame cross-beam. The clutch-bar if is further supported bythe horizontal rod y, passing through a proper opening in same and connected to the end frames, which rod carries spiral springs z, bearing between the end frames and the clutch-bar t, to return and keep the bar and clutch-collar G in its normal central position midway between the two miter-gears F F'. It will be evident from this construction that a downward pressure on either end of the foot-trcadlc will shift the clutch-collar G to couple the corresponding miter-gear to the main shaft and rotate the clamp-screwY to raise or lower the clamp-plate O', as may be desired.

Hinged at one corner of the clamp-table is a lever-bar Z1', provided with a handle c', by means of which the clamp-table and the piles of paper maybe turned quarter-way around, when at rest, the lever and table being held stationary in the lugs d' d', bolted to the bedplate in front at each corner.

The operator having placed two books or bundles of paper in the clamp with the uncut edges outward, pattern-boards l) 2J and 2)/ 1)/ are selected of a size required for the trimmed books. The upper patterns p p' form gageblocks for the cutting-knives in the following manner: As already described, the knife-carriages and knives are mounted on the knifebed E to move horizontally. Passinghorizontally through each of the depending knifeplates G G and serving as a lateral guide therefor is the rod c. Surrounding this rod are the spiral springs f f', bearing between the knife-plates and the collars g g', adjustable along the rods, to vary the tension of the springs, by set-screws. The effect of these springs is to press the knives into close contact with the upper pattern-boards p p of the clamp. Now when the knife-actuating mechanism is set in operation and the side edges of the books have been cntand trimmed the operator raises the handle c and swings the clamp-table one-quarter of a turn to bring the other uncut edges under the knives, locking the table in its secured position, as above described. In order to accomplish this turning of the clamp-table, it is necessary that the cutting-knives should recede from their position in contact with the pattern-boards p p. For this reason the corners of these pattern-boards arc rounded, as shown in Fig. 5, and as the clamp-table is turned the pattern-boards press back the knives under the pressure of the springsff, the spring-pressure causing the knives to take position with the turning of the clamp-table in contact with the end edges of the pattern in position to form the second cut. Thus no matter what the size or shape of the patterns the knives automatically adjust themselves for any pattern selected. It will be seen that not only can two books or packages be trimmed simultaneously, but that the trimming is accomplished with a single turn of the table and two operations of the knives, a saving of fifty per cent. in time and labor over all machines where a single knife is employed. But not only in this is my present IOO IIO

machine of great advantage and utility, but l the cuts may be made with absolute accuracy and uniformity, and the position of the uncut is then necessary to stop the machine in orbooks with reference to the cutting-knives may be accurately iiXed without guesswork by means of the gage now to be described.

Heretofore there has been' no room for a gage for placing the packages in the clamp in the machines in which a single knife is employed, for four quarter-turns must be given to the paper in such machines to bring each edge under the knife; but with my machine, inasmuch as two side cuts are made simultaneously and onlya single quarter-turn is nec- V essary, a gage can be provided at the rear of the cutting-table.

L' is a gage-block provided with two vertical faces, one for each book or package. Extending back horizontally from the rear lower edge of this block is a slotted arm h' for the adjustable attachment of a gage-block to a vertical rod Z', which rod is hinged to swing in a vertical plane 0n the stud m', extending out from the boss m', secured to the frame. The lower end of this rod Z' is slotted at n' to receive the end of a rod p3, connected with the front cross-beam of a frame and carrying a spiral spring r', whose tendency is to keep the rod l' and gage-block L' in a vertical po.- sition, but to allow the rod Z' to swing on its pivot. Journaled in the boss M' is a vertical shaft or rod N', carrying on its upper end an inwardly-extending arm s', provided with a roller t'.

The rear side and edge of the clamp-table A' is provided with a cam-plate P', as shown in Fig. 5, the cam being provided with such a curve that the moment the clamp-table A' is shifted to turn the paper the cam-surface will contact with the roller 15' and rotate the shaft N'.

Underneath the arm s' is another arm u' on the shaft N', which bears against a frictionroller 'y' on the rod Z', so that the rotation of the shaft N' will swing back the rod Z' and the gage-block L' away-from a position to interfere with the shifting of the clamp-table, the gage being returned to its normal position by the pressure of the spring r' as soon as the cam-surface has passedv the roller t'. As already stated, the gage can be adj usted for any desired sized book or package of paper, and the operator in adjusting the books for the clamps has an accurate gage with the gageblock and the vertical guide-rods B' B' of the clamp.

For starting the machine I mount on the main driving-shaft K the pulley R', secured byset-screws to the gear N. Within this pulley and keyed to the shaft K is a split band' d", expanded in the usual way to couple the pulley and gear N to the driving shaft by the sliding feathered clutch-collar h", provided with a circumferential groove and engaged by the bifurcated ends of the hand-lever S', pivoted in a suitable support on the frame. It is evident that when the machine is started one revolution of the'gear O will cause one reciprocation of the cutting-knives, and as it der to shift the clamp-table I secure the beveled lug c" to the inner edge of the rim of the gear O, which with each revolution of the gear-wheel strikes against the rod d", connected with the lower end of the hand-lever S', so as to shift the clutch and disconnect the gear N from the driving-shaft K. In order to insure the instant stopping of this gear at the end of each knife-stroke, I pass over the outer face of the pulley R' the friction-band e", secured tothe frame at one end and to the rod f" at the other. This rod passes through its su pporting-bracket g" and carries a spiral spring h" on its outer end bearing between the bracket and an adjustable nut Z" thereon, so that there is a constant tension on the pulley R', and the moment the friction-clutch is released any momentum of the gearing is instantly stopped.

In order to prevent any springing of the supporting-standards B B of the frame and to brace and sustain same, I pass the rod T' through the head-blocks D D from side to side and mount on the ends thereof strong spiral springs m" fm", bearing between the sides of the head-blocks andthe adjustable nuts n" n" on the rods, so that tension may always be maintained between the side supports.

In order that the shavin gs of paper trimmed from the edges of the books may not pile up on the operating-table and interfere with and clog the operating mechanism, I slope off the bed-plate toward the base of the frame, as shown at 19" p", and I also provide a sheetmetal guard fr" r" on each side of the bedplate, so that the shavings will be carried down off the rear of the machine.

The operation of the machine and its many advantages will be sufficiently manifest from the foregoing description.

For the purpose of adjusting the knives by hand I provide the hand-wheel M, which is keyed to the driving-shaft K, so that before the power is applied by belt to the drivingpulley L the knives can be raised and lowered by turning the hand-wheel, or a loose and tight pulley can be used instead of a single driving-pulley L.
